Jameson/TVD格式应用旋翼翼型绕流分析
Jameson/TVD Schemes Applied to Simulating the Flow around Rotor Aerofoil
-
摘要: 以一种常见的旋翼翼型为例, 探讨了两种旋翼桨叶翼型绕流数值模拟方法, 即 Jameson有限体积中心格式和有限体积通量修正 Jameson/ TVD混合格式。这两种格式的方法都采用有限体积法进行离散, 并用龙格—库塔时间推进法求解。通过算例分析, 比较了这两种方法的特点。Abstract: Two methods based on Jameson scheme and Jameson/flux correction TVD (Total Variation Diminishing) mixed scheme are constructed to simulate the flow around rotor airfoil.By using finite volume approach for numerical approximation and Runge Kutta time stepping advance,Euler/Navier Stokes equations are solved.Through the analyses of examples,the characteristics of these two methods are concluded.Also,these methods can be further developed to simulate the turbulent flow around helicopter rotor and to calculate helicopter rotor drag and power.
